2006 Infiniti FX I (facelift 2006) Dimensions, Size & Specs

The Infiniti FX I facelift weighs in at a curb weight of 2005 kg, equivalent to roughly 4421 pounds. Its maximum permissible weight — which includes passengers and cargo — is 2478 kg or about 5462 pounds. This weight class indicates a vehicle built with sturdy construction and luxury appointments, while offering a robust SUV driving experience.

With the rear seats in place, the 2006 FX I facelift offers a luggage capacity of 776 liters (around 27.4 cubic feet). When the rear seats are folded down, this capacity expands generously to 1826 liters (approximately 64.5 cubic feet). This spacious cargo volume makes the FX practical for family travel, sports gear, or large shopping hauls.

Standard residential garages typically measure about 2440 mm to 2740 mm in width (8 to 9 feet), and at least 4877 mm in depth (16 feet). The Infiniti FX I facelift's width of 1925 mm (75.8 inches) and length of 4803 mm (189.1 inches) mean it fits comfortably within these garage dimensions with some space to spare on all sides. Height clearance, at 1674 mm (65.9 inches), is also well within the typical garage door height, so this SUV is suitable for standard home garages without specialized modifications.

The factory tire size for the Infiniti FX I facelift is 265/50 R20. This means the tires are 265 mm wide, with a aspect ratio (sidewall height) of 50% of the width, mounted on 20-inch rims. Larger 20-inch wheels with wide tires tend to improve cornering stability and road grip, enhancing sporty handling characteristics. However, tire stiffness may slightly reduce ride comfort compared to smaller wheels with taller sidewalls. This tire sizing aligns with the FX's design focus as a crossover SUV combining luxury, sportiness, and good road manners.

Compared to the original Infiniti FX (2003-2005), the facelifted 2006-2008 FX I maintained the same general footprint, with a length around 4800 mm and width close to 1925 mm. However, minor design tweaks slightly altered styling and aerodynamics without significantly changing exterior dimensions. The weight remained similar as well, with curb weights just over 2000 kg. The facelift focused more on cosmetic upgrades and interior improvements than size changes, retaining the distinct sporty mid-size SUV profile.

The Infiniti FX I facelift sits squarely in the midsize luxury SUV segment with its 4803 mm length and 1925 mm width. For comparison, competitors like the BMW X5 (E70) have lengths around 4850 mm (191 in) and widths near 1933 mm (76 in), while the Porsche Cayenne is roughly 4806 mm long and 1939 mm wide. The FX offers competitive dimensions with a sporty stance, slightly lower height at 1674 mm compared to some rivals, which adds to its more coupe-like design. Its large cargo capacity also compares favorably for versatility in the class.

The Infiniti FX I facelift's dimensions support a spacious and comfortable interior cabin. Its width of 1925 mm (75.8 inches) allows for roomy front and rear seating configurations. Height at 1674 mm (65.9 inches) provides ample headroom, though the FX’s sleek roofline styling may slightly reduce rear passenger headroom relative to taller SUVs. The generous luggage capacity with rear seats folded to 1826 liters (64.5 cubic feet) extends interior utility significantly, making it well-suited for passengers who need both luxury and practical cargo space.

The Infiniti FX I facelift (2006-2008) served as a refreshed version of the original FX, enhancing styling with updated front and rear fascias, revised headlamps, and new taillights for a more modern appearance. The vehicle retained its sporty crossover profile, combining athletic handling with SUV practicality. Technological improvements included upgraded audio and navigation systems, luxury leather interiors, and advanced safety features for its time, such as stability control and multiple airbags. It remained popular for blending dynamic driving with upscale refinement.

With a length of 4803 mm (189.1 inches) and a curb weight of about 2005 kg (4421 lbs), the Infiniti FX I facelift is relatively large but still manageable in urban environments. Its size requires some attention for tight parking spots typical in cities, but the FX benefits from responsive steering and available parking aids in many trims. The moderately wide body at 1925 mm (75.8 inches) means clearance in narrow spaces can be a consideration, but not excessively so for a vehicle of its class. Drivers appreciate its balance of road presence without being overly cumbersome for urban driving.
